Question 1

A microscope shows a thin plant leaf cell with a green organelle packed along the cell edges. Which process is this organelle specialized to carry out?

Filtering wastes from the plant’s blood Photosynthesis using light energy to build sugars Producing sound waves for communication Contracting to move the whole plant

Correct Answer:

Photosynthesis using light energy to build sugars

Question 2

Which statement best describes a cell as the basic unit of life?

All living things are made of one or more cells that carry out life processes Cells are energy waves that leave no mass when measured Only animals have cells; plants are built only of nonliving minerals A cell is any rock fragment smaller than one millimeter

Correct Answer:

All living things are made of one or more cells that carry out life processes

Question 3

A student models a cell membrane with a plastic bag that lets water and small sugar molecules pass but keeps large starch clumps inside. What property of the real membrane is this model meant to represent?

A permanent seal so the cell can never exchange materials Rigid hardness that never allows any substance to cross The ability of membranes to produce their own light Selective permeability that controls what enters and leaves the cell

Correct Answer:

Selective permeability that controls what enters and leaves the cell

Question 4

Mitochondria are more numerous in muscle cells that do a lot of work than in skin cells that do less work. What does this difference best support?

Cells that need more usable energy contain more mitochondria to release energy from food molecules Mitochondria store genetic instructions instead of releasing energy Skin cells do not need any energy at all Mitochondria only appear in nonliving cells

Correct Answer:

Cells that need more usable energy contain more mitochondria to release energy from food molecules

Question 5

During cellular respiration, cells break down sugar molecules. Which statement best describes what happens to the energy?

Energy is created from nothing when the cell wishes to move The sugar’s mass is destroyed completely and no products remain The cell converts sugar directly into new atoms of iron Chemical energy in sugar is released in a form the cell can use for life processes

Correct Answer:

Chemical energy in sugar is released in a form the cell can use for life processes
