Flashcards in Biology Deck (17):
1

What are some differences between a plant cell and an animal cell?

-Plant cells have chloroplasts, larger vacuoles, and a cell wall
-They both have a mitochondria, nucleus, and a cytoplasm. Etc
-Animal cells have a cell membrane, they are motile, and have lysosomes

2

What are the two organ systems in plants?

1. Root System
- Draws water/minerals
- Below ground
2. Shoot System
-Above ground
-tubers
—swollen stem-stores food

3

Explain the order from atoms to organisms

Cell-tissue-organ-organ system-organism

4

Define cellular respiration

Breakdown of glucose to make chemical energy—

5

3 types of passive transport?

1. Diffusion
-move from high to low
- with concentration gradient
2. Osmosis
-diffusion in a liquid
-no energy
3. Facilitated diffusion
-transports proteins

6

Explain active transport

-requires energy (ATP)
-against concentration gradient

7

Define geo/gravitropism

Growth response to gravity

8

Define stomata

Pores that allow gasses to pass through the leaf epidermis

9

Define transpiration

-stomata controls it
-loss of water through leaves from evaporation

10

Who disapproved spontaneous generation? How?

-Louis Pasteur and Francesco Reid
-Open/close flask—mood/no mood
-open/closed/cloth jar—maggots/no maggots

11

What does the xylem do?

Conducts water from roots to leaves

12

What is the cell theory?

1. All living things are made up of 1 or more cells
2.smallest unit of life
3. Must come from pre-existing life

13

What does the phloem do?

Conducts food from leaves to rest of plant

14

What are the 3 types of tissue of tissue in a plant

1. Dermal
-outer layer
-cuticle and epidermis
2. Ground
-bulk of the leaf
-storage and photosynthesis
3. Vascular
-Xylem and Phloem
-Water/food transport

15

Explain spontaneous generation

Theory that life could emerge spontaneously from non-living matter

16

3 types of osmosis

1. Hypertonic
-Shrinks
2. Isotonic
-Same
3. Hypotonic
-Enlarged

17

Define phototropism

Growth response to light
