The part of a microscope where items to be viewed are placed.
What is the stage
100
This organelle is a small grain-like body that produces proteins inside a cell
What is ribosome
100
A cell makes a copy of its DNA during this stage
What is interphase
100
In this stage of the cell cycle, two cylindrical structures called centrioles are copied
What is Interphase
100
Baby cubs growing into big lions are an example of this function of cell division.
What is the growth function
200
When focusing a specimen you should start with this objective.
What is low objective
200
This organelle is the control center of the cell
What is a nucleus
200
During cytokinesis in plant cells this forms across the middle of the cell
What is a cell plate
200
In this phase of mitosis nuclei are forming: spindle fibers have disappeared: the cell is pinched around its middle
What is Telephase
200
Obtaining and using energy from food and removing wastes are two processes that help cells maintain this
What is homeostasis.
300
This type of microscope uses a beam of electrons to produce a magnified image
What is an electron microscope
300
This organelle receives proteins and other substances and packages them up
What is the golgi apparatus
300
A cell's nucleus divides to form two identical nuclei in this stage of the cell cycle
What is mitosis
300
In this stage of mitosis chromosomes in the nucleus condense, the pairs of centrioles move to opposite sides of the nucleus, spindle fibers form a bridge between the ends of the cell and the nuclear envelope breaks down
What is the prophase
300
A group of similar cells that work together to perform a specific function
What is tissue
400
Unlike Hooke, Leeuwenhoek observed cells that
What is were alive
400
These two structures are found in plant cells but are not found in animal cells
What are chloroplast and cell wall
400
In Prophase, these are contained in chromatids
What is DNA
400
This structure holds chromatids together until they move apart later in mitosis
What is a centromere
400
These organelles convert energy from food molecules into energy the cell can use
What are mitochondria
500
The term "resolution" refers to
What is: how well structures close together can be distinguished
500
The process of substances moving through the cell membrane from areas of higher concentration to areas of lower concentration is called
What is diffusion
500
Identify the phases of mitosis in order
What is 1.Prophase 2. Metaphase 3. Anaphase 4. Telophase
500
A replicated chromosome consists of two rod-like parts called
chromotids
500
A substance that cannot be broken down into simpler elements is a(n)
