Biology || Chapter 7 Review...Cell Structure & Function

The work of Schleiden and Schwann can be summarized by saying that

• all plants are made of cells

• all animals are made of cells

• plants and animals have specialized cells

• all plants and animals are made of cells

Which cell structure contains the cell's genetic material and controls many of the cell's activities?

• organelle

• cell envelope

• nucleus

• cytoplasm

Cells fall into two broad categories, depending on whether they

• have a cell wall

• contain genetic material

• have a nucleus

• contain chloroplasts

Eukaryotes usually contain

• a nucleus

• specialized organelles

• genetic material

• all answers are correct

Which structures carry out cell movement?

• cytoplasm and ribosomes

• nucleolus and nucleus

• microtubules and microfilaments

• chromosomes

Which organelle breaks down compounds into small particles that the cell can use?

• Golgi apparatus

• endoplasmic reticulum (ER)

• lysosome

• mitochondria

Which organelle makes proteins using coded instructions that come from the nucleus?

• Golgi apparatus

• mitochondrion

  (plural: mitochondria)

• vacuole

• ribosome

Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use?

• chloroplast

• endoplasmic reticulum (ER)

• Golgi apparatus

• mitochondrion (plural: mitochondria)

Which of the following is a function of the cell membrane?

• breaks down lipids, carbohydrates, and proteins from food

• stores water, salt, proteins, and carbohydrates

• keeps the cell wall in place

• regulates which materials enter and leave the cell
