Chapter 2 How Cells Function

cellular respiration

Both a whale and a seaweed use which of the following to change glucose into energy?

oxygen

Both plants and animals obtain energy from food by the process of cellular respiration. What substance do plants produce during photosynthesis that is necessary for cellular respiration to take place?

oxidizing agent, oxidizing organic compounds

During cellular respiration, oxygen serves as a(n)

only used in the light-independent reaction

During photosynthesis, carbon dioxide is

the sun

During photosynthesis, plants produce "food" for themselves. When animals eat plants, they take in energy that originally came from:

carbohydrate

During photosynthesis, plants produce glucose, which is a

chemical energy

During photosynthesis, producers convert energy from the sun into

energy

Grass produces glucose during photosynthesis. A cow eats grass. When the cow breaks down the glucose, what is being supplied to the cow from the grass?

chloroplast

In a plant cell, which organelle is the site of photosynthesis?

oxygen

In fermentation, cells release energy without

light energy

Leaf cells use chlorophyll to absorb

mitochondria

Which organelle is the site of cellular respiration?

chlorophyll

Which plant pigment traps most of the light energy used in photosynthesis?

photosynthesis

Which process occurs in chloroplasts?

osmosis

Which word means" diffusion of water across cell membranes?

lipid

are found in the fats, oils and waxes used for structure and to store energy

nucleic acid

A type of molecule, made up of subunits of nucleotide, that is part of the genetic material of a cell and is needed to make proteins

chloroplasts

Animal cells cannot carry out photosynthesis because they lack

water

Osmosis is the diffusion of ______ into or out of the cell through the cell membrane

Photosynthesis produces oxygen while respiration produces carbon dioxide.

Photosynthesis and respiration both occur in plant cells as two important chemical processes. What are the differences in the processes?

cellular respiration

The cells of a redwood tree require oxygen for the process of

lipids

The fats, oils and waxes found in living things are known as

active transport

The movement of materials across a cell membrane, requiring energy, is called

chemical reaction

The process by which chemical changes occur

leaf

Where on a plant does photosynthesis take place?

organic carbon

Which of the following is a product of photosynthesis

CO2 (carbon dioxide) and H2O (water)

What are C6H12O6 (glucose) and O2 (oxygen) converted into in cellular respiration

O2 (oxygen) and C6H12O6 (glucose)

What are carbon dioxide (CO2) and water (H2O) converted into as a result of photosynthesis

proteins

What do cells use as a source of energy and for energy storage?

protein

control the chemical activity of a cell and support growth and repair.
