How are leaf cells and root cells different? (1 point).

Question

Responses

Leaf cells can absorb nutrients from the air, but root cells require soil to absorb nutrients.
Leaf cells can absorb nutrients from the air, but root cells require soil to absorb nutrients.

Leaf cells have chloroplasts, but root cells do not.
Leaf cells have chloroplasts, but root cells do not.

Leaf cells have nuclei, but root cells do not.
Leaf cells have nuclei, but root cells do not.

Leaf cells can reproduce, but root cells cannot.

Answer 1

The correct response is: Leaf cells have chloroplasts, but root cells do not.

Leaf cells are responsible for photosynthesis and contain chloroplasts, which are needed for this process, while root cells do not have chloroplasts as they do not participate in photosynthesis.

Answer 4

What made the discovery of cells possible?(1 point)
Responses

the study of viruses and bacteria
the study of viruses and bacteria

the invention of the microscope
the invention of the microscope

the observation of cells by Hooke and Pasteur
the observation of cells by Hooke and Pasteur

the use of magnifying glasses

Answer 5

The correct response is the invention of the microscope.

Answer 6

If a particular cell is known to be round and incapable of producing its own food, which one of these organelles would you assume the cell must have?(1 point)
Responses

central vacuole
central vacuole

plasma membrane
plasma membrane

chloroplast
chloroplast

cell wall

Answer 7

The correct response is plasma membrane.

Since the cell is described as round and incapable of producing its own food, it would definitely have a plasma membrane. Chloroplasts are involved in photosynthesis and are found in cells that can produce their own food, while central vacuoles and cell walls are not universal to all cell types.

Answer 8

Unicellular cells must carry out ___ of life.(1 point)
Responses

a few functions
a few functions

a single function
a single function

specific functions
specific functions

all functions

Answer 9

The correct response is all functions.

Unicellular organisms must carry out all functions of life (such as metabolism, response to stimuli, and reproduction) within a single cell.

Answer 10

Which statement about multicellular organisms is correct? (1 point)
Responses

Cells in multicellular organisms can reproduce by binary fission.
Cells in multicellular organisms can reproduce by binary fission.

A multicellular organism has many specialized cells.
A multicellular organism has many specialized cells.

Every cell of a multicellular organism is responsible for movement.
Every cell of a multicellular organism is responsible for movement.

The cells of a multicellular organism must perform all life functions.

Answer 11

The correct response is A multicellular organism has many specialized cells.

Multicellular organisms consist of various types of specialized cells that perform specific functions, whereas the other statements are not accurate.
