Dermal tissue- outer surface

Vascular tissue- tranports water and nutrients

Front 7

Root system

Back 7

Part of plant that typically grows underground that absorbs water and minerals using root hairs and stores food

Front 8

Back 8

Stores nutrients

Source of food

Remedies

Front 9

Shoot system

Back 9

Conducts photosynthesis and reproduces sexually

Front 10

Function of leaf

Back 10

PHOTOSYNTHESIS

support

Protect

Reproduce

Atrract

Front 11

Structure of cell that performs photosynthesis

Back 11

Chloroplast contain thylakoid which a flat and disk like. Thylakoid are aranged in stacks called grana. Grana traps solar energy and begins converstion

Front 12

Function of flower

Back 12

Reproduce

Front 13

How is plant pollination is achieved

Back 13

The male reproductive structure produce pollen and the female reproductive structure produce eggs. When the eggs get fertilized by pollen; pollination occurs.

Front 14

Stem function

Back 14

Supports leaves flowers

Medicine

Path to transport materials

Vascular tissue to carry substances

Food storage

Protects photosynthesis and reproduction

Front 15

Seed growth process

Back 15

Cells divide quickly and develop into an embryo where they differentiate into specific tissue

Front 16

Region of growth**

Back 16

Tips of roots and shoots

Below the surface of the stem in woody plants

Front 17

Why does plant growth occur**

Back 17

Undifferentiated cells are actively growing and dividing. They specialize and develop features according to their location and future function

Front 18

Meristematic cell**

Back 18

Indifferentiated cell that can form a specialized cell

Front 19

Tissue in leaf diagram

Back 19

Front 20

Tissue in stem diagram

Back 20

Front 21

Tissue in root diagram

Back 21

Front 22

Dermal tissue

Back 22

Covers the entire outer surface of plant and includes the epidermal and periderm tissue

Front 23

Vascular tissue

Back 23

Joins plant parts and transportation system for water minerals and other chemicals

Front 24

Ground tissue

Back 24

All internal tissue in the root stem and leaves

Front 25

Epidermal tissue

Back 25

Thin layer of the cells that covers the surface of leaves stems and roots

Front 26

Periderm

Back 26

Forms bark on stems and large roots om woody plants

Front 27

Xylem**

Back 27

Made up of elongated cells. It transports dissolved minerals, water and nutrients upward starting at the the roots

Front 28

Phloem**

Back 28

Tissue that transports solutions of sugar produced by photosynthesis and other dissolved nutrients and hormones. They can be transport either downward starting at the leaf or upward starting from the root.

Front 29

Ground tissue**

Back 29

Filter between dermal and vascular tissue

In green plants: manufacture nutrients by photosynthesis

In roots: store carbohydrates

In stems: provide energy and support

Front 30

Remaining sugar is called

Back 30

Starch

Front 31

Palisade layer

Back 31

A type a ground tissue located below the upper suface of a leaf that are closely packed woth chloroplasts

Front 32

Spongy mesophyll

Back 32

Loosely packed cells containing chloroplasts in the middle of a leaf

Front 33

Leaf cross section

Back 33

Front 34

Cuticle

Back 34

Layer of wax that blocks gas and water diffusion

Front 35

Stomate

Back 35

Opening in surface of the leaf that allows gas exchange

Front 36

Guard cell

Back 36

One of a pair of cells in the epidermis that surrounds and controls the opening and closing of each stomate

Front 37

Obtaining water process

Back 37

Root hairs exend from the roots into the soil. These root hairs absorb water through osmisis. The water travels from the roots up to the stem through the leaf via the xylem

Front 38

Obtaining food and transporting it within an ANIMAL orgamism

Back 38

The nervous system and musculoskeletal system allow the body to obtain the the food. Then the digestive system digests it and the circulatory system transport the nutrients via blood vessels

Front 39

Obtaining food and transporting it with a PLANT tissue

Back 39

The entry of carbon dioxide water and light energy is controlled by the dermal tissue. Then the ground tissue cells in leaves produce sugar (their food). Then the vascular system transport the food i the phloem

Front 40

Cell division in plants

Back 40

Only in certain areas and once it has differentiated it does not divude any further

Front 41

How do plants grow

Back 41

By Using unspecialized cells called meristem

Front 42

Apical meristem

Back 42

Undifferentiated cells at the tips of the roots and shoots

Front 43

Lateral meristem

Back 43

Undifferentiated cells under the bark in the stems and roots of woodu plants

Front 44

Where and how does cell division occur in a plant

Back 44

In the apical meristem the cells elongaterhen differentiate into various kinds of specialized tissue and mature

Front 45

Growth in diameter

Back 45

The outer meristem produces new dermal tissue called cork to replace old epidermal cells. The inner lateral meristem produces new phloem on its outer surface and new xylem on its inner surface.

Vegetation reproduction process

Back 46

Runners are shoots that grow away from parent plant. Once they touch the ground they put down roots and form an identical plant
