Life Sciences Grade 10 - Cells: The Basic Unit of Life

Flashcards related to cells, their structure, and function

Organelles

Small structures that are found in the cell that carry out various functions

Cells

These are the basic unit of life

Microscopic cells

Are so small they cannot be seen with the naked eye

Macroscopic cells

Are large enough to be seen with the naked eye

Diffusion

Is the movement of liquid or gas particles from a region of high concentration to a region of low concentration until equilibrium is reached

Osmosis

Is the movement of a liquid from a region of high concentration to a region of low concentration across a differentially permeable membrane until equilibrium is reached

Endosmosis

Is when water enters a cell by osmosis

Exosmosis

Is when water leaves a cell by osmosis

Active transport

Is when a substance is moved or absorbed against a concentration gradient and it requires energy

Cellular respiration

Is the process during which energy is released

Intra

Means within

Intracellular

Means within the cell

Inter

Means between

Intercellular

Means between the cells

Intracellular digestion

Is digestion that occurs within the cell
