Plants

SC.912.L.14.7 Relate the structure of each of the major plant

organs and tissues to physiological processes.

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

Plant Organs

Roots: anchor, absorb water, store

food

Stems: support, transport

Leaves: photosynthesis, produces

food

Flowers, Fruits, Cones: reproduction

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

This is NOT on your packet so you may want to add!

Pistil – female

Stamen – male

Be able to label the

diagram!

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

Plant Tissues

Meristematic: regions of rapidly dividing cells

Ground: consist of parenchyma, sclerenchyma, and

collenchyma cells that have diverse functions

Dermal: makes up outer covering of the plant

Vascular: xylem (transports water), phloem (transports

food)

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.Other Structures

Cambium: meristematic tissues that run the length of the roots and stems and produces new cells for growth

Guard Cells: pair of cells that open and close a plant’s stomata to allow gas exchange and transpiration

Phloem: transport of nutrients

Seed: reproductive structure of some vascular plants

Stomata: openings on the bottom of a leaf that allow gas exchange and transpiration

Xylem: transport of water

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

You must know how each tissue and organs helps the plant

to carry out the following processes:

Photosynthesis

Cellular Respiration

Transpiration (evaporation of water from leaves)

Growth

Reproduction

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

Photosynthesis: carried out in the

chloroplasts; dermal tissue

contains stomata (pores in leaves

which allow gases and water in

and out)

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

Cellular Respiration: carried

out in mitochondria in cells

found throughout the plant

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

Transpiration: carried out in the

leaves; dermal tissue contains

stomata surround by guard cells

which open and close to allow

water to evaporate from the leaves

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

Growth: meristematic tissue is the region of

growth in plants; cambium (found in the

stem) contains meristematic cells as well as

root cap

Reproduction: flowers, fruits, and cones

contain reproductive organs for different

kinds of plants

1. Students will explain how the structures of

plant tissues and organs are directly related to

their roles in physiological processes.

Reproduction In Plants:

Spore Producing Plants: nonvascular, produce spores, remain

small, absorb water through osmosis, live in moist environments

Vascular Plants: some produce spores, but most use flowers, fruits,

or cones to reproduce, contain vascular tissues (xylem and

phloem)

Gymnosperms: cone-bearing

Angiosperms: flowers and fruits
