Ch. 3-4 - cell structure and function, photosynthesis and respiration

A cell that has a hypertonic salt solution will

loose salt

The basic unit of structure and function in living things is the

cell

What is an example of active transport

endocytosis

The nucleolus is made up of

Proteins and RNA

If you observe several cells with a nuclei under the microscope, you are probably observing cells that are

Eukaryotic

Two organelles that are common to plant and not to animal cells are

Cell walls and chloroplasts

What is not a characteristic of a prokaryotic cells

Very complex

What term includes all the others: passive transport, diffusion, osmosis, or facilitated diffusion

Passive transport

Which way will the water travel through the membrane? L:3% R: 10%

Right

If the membrane is permeable to the salt which way will the salt move? L:3% R:10%

Left

Which is the hypertonic solution? L:3% R:10%

Right

If the solution became isotonic, which way would the water move? L:3% R:10%

Both

The process by which molecules of a substance move from areas of low concentration of the substance to areas of higher concentration is

Active transport

What is the purpose of the carbohydrates in the cell membrane

Identification carbohydrates

The work of Schleiden and Schwann can be summarized by saying

Plants and animals are made of cells
