|
Mention the main structures of plants and also mention the additional part of plants |
main parts = Root, Stem, Leaves additional parts = flower, fruit, seed |
|
|
Mention 3 parts in root and explanation!
|
1. Cell division : divide into apical and meristem 2. Elongation 3. Differentiation : root hairs |
|
|
what is the meaning and the function of cuticula
|
zat lilin, Function is to reduce evaporation
|
|
|
Mention the process of photosynthesis and the kind of plants that work on that process! |
CO2 [xylem] + H2O [xylem] {(sunlight and chlorophyll)} [palisade] become C6H1206 [phloem] + O2[sponge tissue] + H2O [sponge tissue]
|
|
|
Parts of plants where the photosynthesis won't happen is .......... and the part of plant that have the most photosynthesis is ......... and why?
|
Vascular bundle, Palisade, In palisade there is so much chlorophyll
|
|
|
Functions of root
|
1. Food storage 2. To absorb water and mineral 3. For respiratory tool 4. attach the plant to the soil |
|
|
Root structure is divided by 2, mention and different it between them!
|
1. Fibrous root - monocot - branching roots - grow close to the surface 2. Tap root - dicotyl - strong roots - grow deep in soil |
|
|
what is the function of xylem and phloem?
|
xylem : transports water and minerals from roots - stem - leaves phloem : carrying water and nutrients from leaves to all parts of the plant |
|
|
there are 2 structure in root, mention and explain!
|
a. External structure consist of root hairs and root cap (calyptra) b. Internal structure consist of (in order from outside to inside) is epidermis, cortex, endodermis, stele |
|
|
What is the difference between monocots stem and dicots stem!
|
monocots : 1. pith is absents 2. pericycle is absents 3. vascular bundles are closed 4. vascular bundles are scattered dicots : 1. pith and pericycle are present 3. vascular bundles are open 4. vascular bundles arranged in a ring |
|
|
what is the functions of lenticels (external structure of stem) ?
|
lenticels connect with the inner part of stem and the function is as a place for gas exchange
|
|
|
explain the external parts of the stem (herbaceous plants)
|
The external parts of stem, there is a thin epidermis which has no foam. the epidermis contains stomata so the gas exchange can occurs
|
|
|
the xylem and phloem form a bundle called ........
|
the vascular bundle
|
|
|
Explain vascular bundle of a dicot's stem!
|
In dicot's stem, vascular bundles are arranged in circle. The xylem located inside and the phloem in outside with cambium between them. cambium's cells always splitting. so inward cambium fission (secondary xylem) while outward (secondary phloem). because the activity of cambium dicot's stem grow bigger and influenced by water and nutrients.
|
|
|
Caused of cambium activity, dicot's stems has a clear borders called as ........
|
annual rings
|
|
|
Explain vascular bundle of a monocot system!
|
vascular bundles are scattered and have no cambium. since it has no cambium, the stem of monocot plant won't grow bigger
|
|
|
The functions of stem
|
1. the place which water and minerals pass through from the roots to the leaves 2. protect the plants (thorny stems) 3. store important chemicals or nutrients for the plant |
|
|
Mention how can the veins formed?
|
Leaf is supported by a stalk. A stalk is connected to midvein. The midvein has many branches that form the veins
|
|
|
Why the leaves have a green color?
|
Because there is a chlorophyll inside the chloroplast
|
|
|
Mention 3 kinds of bone leaves and the example! (Leaf external's structure)
|
1. Pinnately netted veins (mango's leaf) 2. Palmately netted veins (papaya's leaf) 3. Parallel venations (corn's leaf) |
|
|
Mention 2 compositions of leaves and also the definition! (Leaf external's structure)
|
1. simple leaves : If the stalk only has one single blade 2. compound leaves : If the stalk have several blades |
|
|
Mention the parts of leaf
|
1. Epidermis, covered by a cuticle; in the lower part of epidermis there is stomata 2. The palisade layer : has many chloroplast 3. The spongy layer : has a vascular bundle of xylem and phloem |
|
|
Mention the function of leaf
|
1. Place of photosynthesis 2. Place for gas exchange |
|
|
The group of plants that produce flower is ..........
|
Anthophyta
|
|
|
Flowers have the same basic structure, mention it! and also the function!
|
1. Sepal (calyx) function : to protect the inner parts of the flower 2. Petal (corolla) function : attract pollinator insects 3. Stamen function : to produce the pollen grains 4. Pistil function : fertilize the seeds in ovaries 5. Flower function function : generative reproductive organ |
|
|
Stamens are ............ reproductive organs, Pistil is .......... reproductive organs
|
the male, the female
|
|
|
Development of true fruits and definition, and also examples!
|
An ovary will develop into fruit and ovules will become seeds if fertilization happens. IF THE FRUIT IS FORMED FROM TISSUES IN THE OVARY, THE FRUIT IS CALLED "A TRUE FRUIT" Examples : mango, papaya, durian, tomato, peanut, and grain |
|
|
The fruit that came from other parts of flower is called ............ and mention the examples!
|
accessory fruit Example : a. Pineapple (an ovary and sepals) b. Cashews (the style of flowers that grows) c. Apples (swollen base of flowers) d. Strawberries (the base of flowers) e. Jackfruit (petals that grow thicker & fleshier) |
|
|
fruit composed of, mention 3!
|
1. seeds 2. fruit flesh 3. fruit wall |
|
|
The fruit wall divided into 3 layers, mention it!
|
1. the outer layer (epicarp) is hard (coconut) 2. the middle layer (mesocarp) is thick and fleshy (mangoes and papayas) 3. the inner layer (endocarp) some are hard, some are thin (rambutan) |
|
|
The definition of true fruits and accessory fruits?
|
- True fruits are formed from tissues in ovary - Accessory fruits are fruits that formed from the ovary and other parts of flower |
|
|
Process of seeds!
|
Seeds are formed as the fertilization in ovary. Inside the ovary, there are ovules. Inside the ovules there is an embryo
|
|
|
The following parts of embryo :
|
1. embryonic root 2. Seed leaves / cotyledon (1st leaves on the plant) 3. The embryonic stem (located above the cotyledon, some of them below the cotyledon) |
|
|
The cotyledon and embryonic stem called ...........
|
epicotyls
|
|
|
Embryo wrapped by 2 layers, mention it!
|
1. The external layer (seed coat) , wrapped seed layer, characteristics : dry and hard 2. The internal layer (endosperm) , functions as food storage |
|
|
The examples of seeds that have endosperm and don't have endosperm!
|
have endosperm (mango), don't have endosperm (peanuts)
|
|
|
There are 2 types of ovules, mention it!
|
1. Ovules that wrapped by an ovary wall, ex : mango, duku, snake fruit 2. Ovules that aren't wrapped by an ovary wall, ex : cycad and pine |
