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
