Flashcards in Science Quiz 1 Scientific Method And Cells Deck (37):
1

What is the definition of independent variable?

Factor adjusted by the experiment

2

What is the dependent variable?

Factor whose value depends on the value of the dependent variable (can be measured)

3

What is a indirect graph?

A relation ship between two values there's and increase in one result in a decrease in other

4

What is direct graph?

A relation ship between two values there's an increase in one result in a increase in the other

5

What is the x in the graph?

Independent variable

6

What is the y?

The dependent variable

7

What is constants

Any condition that are kept the same between control and experimental group are our constants

8

What is a control?

In an experiment it is the standard for comparison

9

What is the experimental group

in an experiment that receives the variable being tested.

10

What is a plasma (cell) membrane?

Wraps around the cell, enclosed the nucleus and cytoplasm of the cell, found in both pro and eukaryotes cells , made up of two fatty layer called lipid bilayer, controls movement of substance in and out of cell

11

What is the cell wall?

Found in both eu and prokaryotes cell (plant and Most bacteria and some protist not animal), surrounds the outside of the plasma membrane, made up of sugars

12

What is a cytoplasm?

The material inside a living cell, includes all organelles except for the nucleus

13

What is a nucleus?

Contains DNA, place where mitosis occurs, DNA controls the function of the cell and produces proteins, contains nucleoli where RNA forms ribosomes in the cytoplasm

14

What are ribosomes?

Located in cytoplasm, puts together amino acid to form proteins, found inside the ER

15

What are proteins

They do most of the work in cells and are required for the regulation of the body's tissue and organs. Some functions include antibody(fight infections), enzyme (perform chemical reaction), structural, transport

16

What is the endoplasmic reticulum?

An organelle, that is made up of passageway to carry protein and other material from one part of the cell to another

17

What are two of the endoplasmic reticulum?

Smooth ER (no ribosomes makes lipids) rough ER ( ribosomes are presents)

18

What is the Golgi body?

Looks like flattened stacks, receives proteins and lipids from the ER, packages them into VESICLES and distributes them throughout the cell

19

What are lysosomes?

Comes from VESICLES made by the Golgi body, contains digestive chemicals that help break down food, debris and bacteria

20

What is the mitochondria?

Carries out celluar respiration using carbohydrates and fats in the cell, produce energy in order for the cell to carry functions, is found in eukaryotes (bacteria does not have mitochondria)

21

What are chloroplasts

Found in prokaryotes and eukaryotes (not in all plants Protists), make food through photosynthesis, this organelle contains green pigment known as chlorophyll, which captures radiant(light) energy in order to make sugar (glucose)

22

What are vacuoles?

Storage bubble, storage food, water, waste, and debris in the cell, waste will be eliminated from the cell through exocytosis(outside)

23

Cell wall

Protects and support the cell

24

Cell membrane

Protects the cell, performs active transport and passive transport, moved materials in and out of cell, communication

25

Cytoplasm

Pad and supports organelles inside the cell. Moves by cyclosis

26

Nucleus

Controls all of the cells activity

27

Nuclear membrane

Covers and protects the nucleus

28

Nuclelous

Produce ribosomes

29

Chromatin

Provides instructions for the cells activities (growth, reproduction)

30

Endoplasmic reticulum

Transport materials like proteins around the cell

31

Ribosomes

Makes proteins

32

Mitochondria

Supplies energy or ATP for the cell through cell respiration using glucose and oxygen

33

Vacuole

Storage tank for food, water, waste or enzymes

34

Chloroplast

Captures sunlight and uses it to produce food through photosynthesis

35

Golgi body

Packages and secrets proteins for use in and out of the cell

36

Lysosomes

Digest older cell parts, food or other objects

37

Centriole

Used with spindle apparatus during mitosis
