Cells Test

The cell theory is one of the unifying themes of biology. Which of the following statements would be part of the cell theory?

• All life is made of cells.

• Cells are the smallest units of life.

• Cells come from preexisting cells.

• All of the above

Which of these organisms has cells with cell walls?

• A bluebird

• A pine tree

• A ladybug

• A Fox Squirrel

When comparing a plant cell to an animal cell, only the plant cell will contain-

• Ribosomes

• Chromosomes

• Chloroplasts

• Mitochondria

What is the primary difference between prokaryotes and eukaryotes?

• The prokaryotes have organelles; the eukaryotes do not.

• The prokaryotes do not have a nucleus; the eukaryotes have a membrane-bound nucleus.

• The prokaryotes make their own food; the eukaryotes do not.

• The prokaryotes have a cell wall; the eukaryotes do not.

Which best describes why this is a cell of a photosynthetic organism

• The cell has a cell membrane

• The cell has chloroplast

• The cell has a nucleus

• The cell has cytoplasm

What will most likely be the result if all of the mitochondria are removed from a plant cell?

• It will be unable to carry out respiration.

• It will lose water through osmosis.

• It will break down the ribosomes in the cell.

• It will be unable to photosynthesize.

What structure inside cells contains the genetic information that is passes from one generation of cells to the next generation of cells?

• Ribosomes

• Nucleus

• Mitochondria

• Chloroplast

One type of cellular reproduction that occurs in the nucleus that results in a duplicate copy of the cell is called:

• Mitosis

• DNA

• Mutation

• Cytoplasm

What is the clear, jelly-like substance that is found inside plant and animal cells called?

• Plasma

• Vacuoles

• Lymph

• Cytoplasm

Which statement best describes a cell wall?

• A cell wall is a large storage area that holds food.

• A cell wall is a cell structure in which food is made.

• A cell wall is a thin layer surrounding a cell that allows water and some minerals to pass into and out of a cell.

• A cell wall provides support and shape for plant cells. It is made mostly of cellulose which provides a protective framework for the cell
