What is the endoplasmic reticulum?
A tubular network that acts as a transport system. Fused to the nuclear membrane and extends into cytoplasm.
How do molecules get into cell if they are not soluble?
Active transport of through vesicles in the membrane
What kind of respiration occurs in the mitochondria?
Aerobic
What are Cilia?
Appendages extending from surface of cell (causes movement)
What happens during prophase?
Chromatin thickens to develop nuclear membrane. Centrioles move to OPPOSITE sides of cell Mitotic spindle moves chromosomes around in cell
What makes up organs?
Collection of tissues
What are between the inner and outer membrane of mitochondria?
Cristae (folds)
What are centrioles?
Cylinder shaped structures near the nucleus used for division.
What is the cell filled with?
Cytoplasm/Cytosol
What do ALL cells contain?
DNA, RNA, and protein synthesis ability
What does the nucleus contain?
DNA, and chromosomes.
What is the cell membrane?
Defines the cell by acting as a barrier
What does the mitochondria do?
Develops ATP, assists cell growth/death
What is gastrulation?
Early process of embryotic cell development of most animals.
Where does the nervous system develop from?
Ectoderm
Name the three layers developed during gastrulation
Ectoderm, mesoderm, endoderm.
Where can ribosomes be embedded?
Endoplasmic reticulum
In what kind of cells are mitochondria numerous?
Eukaryotic Cells
What is the role of the nuclear pores?
Exchange material between nucleus and cytoplasm
Difference between flagella and cilia
Flagella are longer, and cells usually only have one
What do chromosomes store?
Genetic information about the plant or animal
What is an organelle?
Group of complex molecules that help the cell survive
What can the lysosome do?
Help transport undigested substances to membrane so it can be removed
What does the cell membrane do?
Helps keep the cytoplasm inside and foreign substances outside.
When does meiosis happen?
In reproductive cells called gametes
How many membranes does the mitochondria have?
Inner and Outer
Where is the nucleolus found?
Inside of the nucleus
Name the 6 steps in mitosis in order
Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
What is a centrosome?
Involved in mitosis/cell cycle, has a pair of centrioles surrounded by protein
What is a vesicle?
It is a small organelle within a cell.
What is the golgi complex made of?
Layered membrane
What are the layers of the nuclear envelope made of?
Lipids
What is the nucleoplasm?
Liquid within the nucleus (similar to the cytoplasm).
What is cytosol?
Material inside of the cell.
What is the one thing that cells have in common?
Membrane
What is the cytoskeleton made up of?
Microtubules that help shape and support the cell.
What are the two ways a cell can reproduce?
Mitosis and Meiosis
What happens during metaphase?
Mitotic spindle moves to the center, and chromosomes align along the center spindle.
What kind of molecule can usually pass through cell membrane
Molecules that are soluble in phospholipids
What is cytosol made up of?
Mostly water, but can have other floating molecules.
What does the membrane of a vesicle do?
Moves materials within a cell
Where is the golgi complex located?
Near the nucleus.
What does each cylinder centriole have?
Nine groups of three microtubules.
Do neurons grow or divide once mature?
No
Is the cell an exact copy of parent cell in meiosis?
No
What does each cell consist of?
Nucleic acids, cytoplasm, and cell membrane
What molecules typically pass through cell membrane?
Oxygen and Water
What happens during anaphase?
Pairs of chromosomes (sisters), begin to pull apart. Grooves appear in cell membrane
What is a microtubule?
Part of the cytoskeleton to support the cell.
What is the nucleus responsible for?
Passing genetic material between generations.
What is a cell membrane composed of?
Phospholipids
What happens in cytokinesis?
Physical splitting of the cell.
What are microtubules made up of?
Protein
What does the nucleolus consist of?
Protein, lacks a membrane.
What are transport holes
Proteins that help certain molecules and ions move in and out of the cell
What does rough endoplasmic reticulum have?
Ribosomes on the outside
What are vacuoles?
Sacs used for storage, digestion and waste removal
What are the two types of endoplasmic reticulum?
Smooth and Rough
What happens during Telophase?
Spindle deteriorates, nuclear membrane forms, chromosomes revert to chromatin.
What is a lysosome?
Structure that digests proteins, lipids, and carbs.
What is the role of the nucleolus?
Synthesize Protein, stores RNA, synthesizes RNA
What do ribosomes do?
Synthesize proteins from amino acids
What does the Chromatic consist of?
The DNA and protein that make up chromosomes
What happens in interphase?
The cell prepares for division by replicating genetic material
What is the nuclear envelope?
The structure that surrounds the nucleus
How does cell life begin?
With sexual or asexual reproduction
Can animal cells have more than one vacuole?
Yes
Do all eukaryotic cells have a nucleus?
Yes
