Lesson 1
What tool allows us to be able to study cells?
Microscope
list these in order of complexity
Cell, Atom, Tissue, Organ System, molecule, organ
Atom, Molecule, Cell, Tissue, Organ, Organ System
Draw and define Endocytosis.
When a cell engulfs and takes in a large particle
what happens during Anaphase
The chromosomes pull apart into separate chromatids and move to opposite sides of the cell
are Viruses living or nonliving
Nonliving
What happens in the G0 (G zero) phase? What is a type of cell that tends to stay in this phase.
During g zero the cell is resting - it is neither dividing or preparing to divide. Nerve cells stay in this phase - that's why we cannot grow new nerve cells
Who was the first to discover and observe living cells?
Anton van Leeuwenhoek
What organelle makes energy out of food for the cell. Also known as the powerhouse of the cell.
Mitochondria
Draw and define Exocytosis.
When the cel removes large waste particles from the cell
Why do our cells divide (at least 3 functions)?
Grow
Repair
Reproduce
Replace
An crocodile is a _____(eats food)____________ while a Maple tree is a ____(makes own food)_____________.
Heterotroph, Autotroph
Name the 3 principles of the Cell Theory
All Living things are made of Cells
All cells come from existing cells
Cells are the basic unit of structure and functions of living things
What does the nucleus do?
The nucleus is the brain of the cell tell the cell what to do and how it should function
What are the 3 types of passive transport
Diffusion
Osmosis
Facilitated diffusion
What are the 2 major phases of cell division
Mitosis
Cytokinesis
What is it called when unrelated organisms evolve similar characteristics or traits?
Convergent Evolution
What type of tree did Sir Robert Hooke first observer cell in.
Where they living or nonliving
Cork Tree bark
they were nonliving
List the 3 unique organelles in a plant cell?
Cell Wall
Chloroplast
large Vacuole
2 types of active Transport
Endocytosis
Exocytosis
What are the four phases of Mitosis in order?
Prophase
Metaphase
Anaphase
Telophase
Name the 3 domains
Eukarya, Archaea, Bacteria
Which two scientists were credited with developing the cell theory?
Matthias Schleiden and Theodor Schwann
State why a plant cell needs a large vacuole and a plant cell doesn't
A plant cell isn't able to gather water and hunt for food, so it needs to store up materials for times of harsh conditions.
Why do cells allow things to enter and exit the cell?
to get nutrients that are needed for the cell to survive and function, While getting harmful waste out.
list the Cell Cycle in order while explaining what happens in each step.
g0, g1, s,g2,mitosis g0 - rest, g1- active growth/protein synthesis, s - DNA replication, g2 - cell organelles produced, mitosis, cytokenisis
Give me two characteristics of living things?
Made of cells
Contain Similar chemicals and use energy
Respond to their surroundings
Grow, develop and reproduce.
