Section 1

(20 cards)

selectively permeable

Front

a property of cell membranes that allows some substances to pass through, while others cannot

Back

cilia

Front

Hairlike projections that extend from the plasma membrane and are used for locomotion

Back

Eukaryotic

Front

A cell characterized by the presence of a nucleus and other membrane-bound organelles. Eukaryotes can be unicellular (protists) or multicellular (fungi, plants and animals).

Back

Cytoplasm

Front

A jellylike fluid inside the cell in which the organelles are suspended

Back

Chloroplast

Front

An organelle found in plant and algae cells where photosynthesis occurs

Back

Lysosome

Front

cell organelle filled with enzymes needed to break down certain materials in the cell

Back

cell wall

Front

A rigid structure that surrounds the cell membrane and provides support to the cell

Back

Nucleus

Front

Control center of the cell

Back

Golgi apparatus

Front

stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum

Back

Ribosome

Front

Cytoplasmic organelles at which proteins are synthesized.

Back

Organelle

Front

A tiny cell structure that carries out a specific function within the cell

Back

Chlorophyll

Front

A green pigment found in the chloroplasts of plants, algae, and some bacteria

Back

Diffusion

Front

Movement of molecules from an area of higher concentration to an area of lower concentration.

Back

Endoplasmic Reticulum (ER)

Front

An extensive membranous network in eukaryotic cells, continuous with the outer nuclear membrane and composed of ribosome-studded (rough) and ribosome-free (smooth) regions.

Back

active transport

Front

Energy-requiring process that moves material across a cell membrane against a concentration difference

Back

Isotonic

Front

Describes a solution whose solute concentration is equal to the solute concentration inside a cell

Back

Mitochondria

Front

Powerhouse of the cell, organelle that is the site of ATP (energy) production

Back

Prokaryotic

Front

An organism whose cells do not have an enclosed nucleus, such as bacteria.

Back

plasma membrane

Front

A selectively-permeable phospholipid bilayer forming the boundary of the cells

Back

Flagella

Front

whiplike tails found in one-celled organisms to aid in movement
