Total questions: 15

Worksheet time: 8mins

Name
Class
Date
1.

An organelle found in plant and algae cells where photosynthesis occurs and energy is stored.

a)
mitochondria
b)
nucleus
c)

cell wall

d)
chloroplast
2.

What is the process where light energy is converted to simple sugars?

a)
Photosynthesis
b)
Transpiration
c)
Fermentation
d)
Respiration
3.

What 3 elements are abundant in the air and water around them and can be obtained directly from the atmosphere in large amounts?

(Don't forget that nitorgen cannot be obtained directly from the atmosphere: plants need nitorgen-fixing bacteria and mycorhizzal fungi to convert the N2 to a usable form underground.)

a)

Calcium, magnesium, iron (Ca, Mg, Fe)

b)

Helium, carbon, and oxygen (HeCO2)

c)

Nitrogen, phosphorus, potassium (NPK)

d)

Oxygen, carbon, hydrogen (CO2, H2O)

4.

What is the process where WATER moves from an area of higher concentration to an area of lower concentration.

Example: after a good rainshower, water moves from the saturated capillary spaces between soil particles into the root hairs of the plant.

a)
Diffusion
b)
Evaporation
c)
Transpiration
d)
Osmosis
5.

Loss of water vapor from leaves to the atmosphere (highest in rainforests).

The process by which a plant loses water vapor through its stomata.

a)
Transpiration
b)

Photosynthesis

c)
Evaporation
d)

Respiration

6.

Plants using energy in sunlight to carry out chemical reactions like producing sugar to feed the plant.

a)
Fermentation
b)
Transpiration
c)
Photosynthesis
d)
Respiration
7.

CO2 + H2O -> C6H12O6 + O2

carbon dioxide + water = carbohydrates (sugars) + oxygen

a)
Fermentation
b)
Decomposition
c)
Respiration
d)
Photosynthesis
8.

What does a plant need for photosynthesis?

a)
Oxygen, nitrogen, and minerals
b)
Sunlight, glucose, and soil
c)
Carbon monoxide, sunlight, and nutrients
d)
Sunlight, carbon dioxide, and water
9.

What is the process when plants absorb/take in oxygen and release carbon dioxide, water, and energy?

a)
Transpiration
b)
Fermentation
c)
Photosynthesis
d)
Respiration
10.

What is C6H12O6 + O2 → CO2 + H2O + energy (ATP)

carbohydrates (made during photosynthesis) + oxygen =

carbon dioxide + water + energy (ATP to run cellular functions, to replicate, grow, and repair...)

a)
anaerobic respiration
b)
cellular respiration
c)
photosynthesis
d)
fermentation
11.

An organism that can make its own food through photosynthesis (plants, algae, some bacteria).

a)

Producer/Autotroph

b)

Scavenger

c)
Decomposer
d)

Consumer/Heterotroph

12.

An organism that must eat other organisms to obtain energy (animals, fungi, most bacteria).

a)
Herbivore
b)

Consumer/Heterotroph

c)
Carnivore
d)

Producer/Autotroph

13.

What produces the oxygen on planet Earth?

a)
Respiration by animals
b)
Volcanic eruptions
c)

Photosynthesis by plants, algae, and some bacteria

d)
Chemical reactions in the atmosphere
14.

What percent of the air is oxygen?

a)
15%
b)
21%
c)
30%
d)
50%
15.
