Flashcards in Science chapter 2 Deck (14):
1

diffusion

the moment of partials from regions of regions of higher density to lower density

2

osmosis

the diffusion of water through a semipermeable membrane

3

passive transport

the movement of substances across a cell membrane without the use of energy by the cell

4

active transport

the movement of substances across the cell membrane that requires the cell to use energy

5

endocytosis

the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the partial into the cell

6

exocytosis

the process in which a cell resales a particle by enclosing the participle in a vesicle that enclosing the particle in a vesicle that then moves t the cell surface and fuses with the cell membrane

7

photosynthesis

the process in which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food

8

cellular respiration

the process by which cells use oxygen to produce energy from food

9

fermantion

the breakdown of food without the use of oxygen

10

cell cycle

the life cycle of a cell

11

chromosome

chromosome is made of protein and a single molecule of oligonucleotide acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

12

homologous chromosomes

Homologous chromosomes are similar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.

13

mitosis

in Eukaryota cells, a process of cell division the forms two new nuclei, each has the same number of chromosomes

14

cytokineses

the division of the cytoplasm of a cell
