Biol 212- Unit 1: Into: What Is A Plant?

Front 1

What are the general characteristics of a plant?

Back 1

1. Cellulose (cell wall)

2. mostly sexual repro with alternation of generations

3. Most are photosynthetic

4. Most are rooted into substrate and therefore stationary

5. Mostly diploid or polyploid

6. Have true vacuole

7. Mostly multicelled eukaryotes

Front 2

What are the four organs of the angiosperm plant?

Back 2

1. Roots

2. Shoots

3. Leaves

4. Flowers

Front 3

Angiosperm means:

Back 3

Flowering plant

Front 4

Properties of roots:

Back 4

1. absorbs and conduct water upwards

2. can conduct organic compounds up and down

3. can store carbon as carbohydrates

4. anchors the plant and keeps it stationary

5. can form associations with fungi for better absorption (mycorrhizal relationship) or bacteria (nitrogen fixation)

Front 5

properites of shoots (stem):

Back 5

1. can conduct water upward (in the xylem)

2. can conduct organic compounds up and down (in the phloem)

3. forms the main support organs for holding plant up

4. occasionally can be photosynthetic

5. can store carbon.

Front 6

Porperties of leaves:

Back 6

1. main collector of light for photosynthesis (where most photosynthesis occurs)

2. main organ of photosynthesis

3. where water evaporation (transpiration) occurs

4. gas exchange occurs through the stomata of the leaves (lets out oxgen and takes in carbon dioxide)

Front 7

Properties of the reporductive organ (flowers):

Back 7

1. site where fertilization occurs (pollination)

2. site of growth of zygote and surrounding tissues onto embryo, seed and fruit.
