Plant Structures and Functions
I Plants- organisms that typically grow in permanent sites; produce
their own food; provide oxygen for other organisms.
II Plant Parts:
support leaves; stores and carries water and nutrients
to leaves; transport sugar to roots.
makes food; helps exchange gases in the envioronment
through stomata (small openings in the leaves).
absorbs water & minerals; anchors plant to soil;
supports the plant

Examples of Two Root Types
Taproot examples Fibrous roots

Check For Understanding- Think about it!
Make a connection between the two
special parts of a plant cell and the parts
of a plant from the previous slide.

Plant Processes

![Page 9: Introduction to Plants 1 A C… · transpiration in plants to absorption and transpiration in humans? 2-Explain one similarity and one difference between plants and animals with regard](https://reader033.vdocuments.net/reader033/viewer/2022050101/5f4051af527f700d40011c3b/html5/thumbnails/9.jpg)
III Plant Processes
1-Absorption = taking in water 2-
and nutrients
Transpiration = release of
water vapor from stomata in
leaves
![Page 10: Introduction to Plants 1 A C… · transpiration in plants to absorption and transpiration in humans? 2-Explain one similarity and one difference between plants and animals with regard](https://reader033.vdocuments.net/reader033/viewer/2022050101/5f4051af527f700d40011c3b/html5/thumbnails/10.jpg)

3- Photosynthesis = the process (in leaves) of converting light
energy from the Sun to chemical energy (food= glucose)
a) Chloroplasts role = provide chlorophyll
b) Stomata role = allows the exchange of gases .

4- Cellular Respiration= the process that plant cells use to
convert energy stored in glucose into useable chemical energy
-occurs in the cytoplasm/ mitochondria of the cells
- ATP (adenosine triphoshate) = molecule where
energy is stored

IV-TropismsTropisms = plant growth toward or away from an external (outside) stimulus
A- Phototropism = growth toward light
B- Gravitropism = growth to and away from the force of gravity ; first root- grows
downward (pos.); stems/leaves –grow upward (neg.)

C- Thigmotropism = a plants response to touch (coiling
around another plant; roots wrapping around a rock in soil)
