Multicellular organisms are produced from (a) one cell (c) three cells (b) two cells (d) four cells

The fine structures of the cell can be seen with the (a) naked eye (c) phase contrast microscope (b) light microscope (d) electron microscope

The cell's energy is used in the process of (a) passive transport (c) diffusion (b) active transport (d) osmosis

The movement of water across a cell membrane is known as ..3..

Because the cell membrane is highly selective in regard to the materials that can cross its boundary, it is described as being (a) selectively porous (c) selectively fluid (b) selectively permeable (d) selectively solid

Solid particles are ingested by cells through a process known as ..4..

The shrinking of cytoplasm due to the loss of water molecules is known as (a) evaporation (c) diffusion (b) osmosis (d) plasmolysis

Molecules carried to the cell surface by vesicles are foreed out of the cell by the process of (a) exocytosis (c) facilitated transport (b) endocytosis (d) adsorption

All of the material that is outside of the nucleus and inside of the cell membrane is called protoplasm.

The most numerous organelles in the cell are the (a) mitochondria (c) ribosomes (b) lysosomes (d) microtubules

Fluid substances for export outside of the cell are stored temporarily in the membrane of the (a) ribosomes (c) endoplasmic reticulum (b) lysosomes (d) Golgi apparatus

Small storage areas in the cytoplasm of animal cells are known as ..8..

Proteins are synthesized and temporarily stored in the (a) ribosomes (c) nucleoli (b) mitochondria (d) lysosomes

Proteins for export are synthesized by ..9.. that are attached to membranes of the endoplasmic reticulum.

The internal membranes of the mitochondria are known collectively as (a) grana (c) mesosoma (b) thylakoids (d) cristae

The granular stage of the fine threads that are contained in the nucleus during interphase is known as ..10..

Cell sap is stored in areas of plant cells known as (a) lysosomes (c) vesicles (b) centrosomes (d) vacuoles

A type of white blood cell specialized to counteract disease organisms that enter the body is the erythrocyte.

Thylakoids are the same as (a) cristae (c) grana (b) nucleoli (d) stroma

The type of tissue that is specialized to respond to stimuli transmitted by motor nerve cell is (a) blood (c) connective (b) muscle (d) bone

A nonliving matrix is most correctly associated with the type of tissue classified as (a) epithelial (c) connective (b) muscle (d) nerve

The type of tissue that covers and lines organs is ..14.. tissue.

A type of plant tissue specialized for conducting water and its dissolved materials is (a) vascular (c) fundamental (b) epidermal (d) collenchyma

Cells specialized for the carrying of nervous impulses are nerve cells, also known as .. 15.

The two strands that make up a chromosome are the (a) centromeres (c) centrioles (b) chromatids (d) spindle fibers

The red blood cells of birds (a) lack nuclei (c) divide asexually (b) carry out mitosis (d) do not cycle

Passive transport requires (a) a semipermeable membrane (b) chemical energy from ATP (c) heat energy (d) an ion transfer pump

Examples of passive transport are (a) diffusion and osmosis (b) osmosis and endocytosis (c) diffusion and exocytosis (d) endocytosis and exocytosis

Solid particles are engulfed by cells during a process called (a) phagocytosis (c) exocytosis (b) plasmolysis (d) pinocytosis
