|
What is the terminal bud?
|
The Terminal (apical) bud of a plant is the primary growing point located at the apex (tip) of the stem.
Terminal buds have special tissue, called apical meristem, cells that can divide indefinitely and produces all the differentiated tissue, including vegetative and reproductive organs. |
|
What is the axillary bud?

|
What is the pericarp?
|
In fleshy fruits, the outer and often edible layer is the pericarp, which is the tissue that develops from the ovary wall of the flower and surrounds the seeds.
The pericarp itself is typically made up of three distinct layers: the exocarp, which is the most-outside layer or peel, the mesocarp, which is the middle layer or pith, and the endocarp, which is the inner layer surrounding the hollowed ovary or the containing seeds. |
|
What is the endocarp?
|
Endocarp (Gr. "inside" + "fruit"), is a botanical term for the inside layer of the pericarp (or fruit), which directly surrounds the seeds. It may be membranous as in citrus where it is the only part consumed, or thick and hard as in the stone fruits of the family Rosaceae such as peaches, cherries, plums, and apricots.
In nuts, it is the stony layer that surrounds the kernel of pecans, walnuts, etc., and that is removed prior to consumption |
|
What is the mesocarp?
|
Mesocarp (Gr. "middle" + "fruit") or Sarcocarp ("flesh" + "fruit"), is the botanical term for the succulent and fleshy middle layer of the pericarp of drupaceous fruit, between the exocarp and the endocarp; it is usually the part of the fruit that is eaten.
|
|
What is the exocarp?
|
Exocarp (Gr. "outside" + "fruit"), is a botanical term for the outermost layer of the pericarp (or fruit). The exocarp forms the tough outer skin of the fruit, which bears oil glands and pigments. The exocarp is sometimes called the epicarp, or, especially in citruses, the flavedo.
|
|
Define "simple fruit"
|
A simple fruit is from a flower that has only one ovary.
|
|
Define "dry fruit" and "fleshy fruits"
|
Pericarp is dry at maturity in dry fruits. In fleshy fruits the pericarp is fleshy at maturity
|
|
The pericarp does NOT split at maturity.
|

(Stem part) This is an underground storage tissue. EX. Ginger
|
Rhizome
|
|
(Stem part) This part is found abover ground. Ex. Starwberry
|
Stolon
|
|
Tubers
|
Tubers are various types of modified plant structures that are enlarged to store nutrients. They are used by plants to survive the winter or dry months and provide energy and nutrients for regrowth during the next growing season and they are a means of asexual reproduction.[1] Two different groups of tubers are: stem tubers, and root tubers.

Protect flowers when it is still a bud
|
|
Stamen
|
Made up of anther and filament. This is the male part, and it produces pollen grains. Pollen grain produces sperm.

|
A canopy has both female and male plants
