Q

The golgi apparatus functions to _______.

(also known as: golgi complex, golgi body)

A

Package, sort, and ship materials INTO and OUT OF the cell

NOTE: it *does* *NOT* transport around the cell

3
Q

How is a prokaryote different from a eukaryote?

A

Prokaryote - NO nucleus! Only found in bacteria! NO membrane bound organelles! OLDER. SMALLER.

Eukaryote - HAS a nucleus, has membrane bound organelles! BIGGER. Found in more complex organisms (ex. humans)

4
Q

Magnify the image on a microscope

A

Objectives (4x, 10x, 40x)

Eye piece (10x)

Objective x Eyepiece = magnification

(ex. 4x objective x 10x eyepiece = 40 magnification)

6
Q

What is the difference between quantitative and qualitative data/observations?

A

Quantitative - numbers

Qualitative - looks

6
Q

Group of similar cells performing a particular function

A

Tissue

6
Q

The first level of organization that includes abiotic (nonliving) factors

(ex. soil, air, water…)

A

Ecosystem

6
Q

What is the function of the ER (endoplasmic reticulum)?

A

Transportation system (within the cell)

Makes lipids

7
Q

Organelle that performs photosynthesis

A

Chloroplast

8
Q

Contains the DNA; brain of the cell

A

Nucleus

10
Q

What is the smallest unit of life?

A

Cell

11
Q

Why does a scientist publish their work?

A

So that it can be reviewed, verified, and repeated over and over

11
Q

Basic unit of matter

A

Atom

11
Q

A group of different populations that live together in a defined area

A

Community

13
Q

The cell ________ (membrane/wall) is a rigid structure around the outside of the cell

A

Wall

14
Q

What are the 8 characteristics of living things?

A
  1. Made of cells 2. Reproduce
  2. Have DNA 4. Grow and Develop
  3. Obtain and Use Energy 6. Evolve
  4. Maintain Homeostasis
  5. Respond to Environment
15
Q

What usually starts scientific work?

A

Careful Observations

(followed by a question - aka hypothesis)

17
Q

What is a population?

A

A group of similar individuals (of the same species) in the same area

18
Q

Collection of living matter surrounded by a barrier

A

Cell

18
Q

Made up of lipids

A

Cell membrane

19
Q

Part of the microscope used to light up the specimen

A

Light source

20
Q

First scientist to see cells (founded them), AND named them

A

Hooke

22
Q

Living things with the ability to function independently

A

Organism

23
Q

After each lab, what should you do?

A

Wash your hands

25
Q

What are the two organelles used for movement? How are they different?

A

Cilia - small hair-like structures that are found outside the entire cell
Flagella - long, whip-like tails found outside the cell in small numbers (1-3)

26
Q

Relatively constant internal conditions

A

Homeostasis
