Cell Theory
All living things are made up on one or more of these things
Cells
This organelle surrounds the cell and is responsible for controlling what enters and exits the cell
Cell membrane
Diffusion is the principle that particles will naturally travel from areas of ___ concentration to ____ concentration
High, low
Cells reproduce via this method of reproduction
Asexual
Mitosis is defined as the division of what molecule(s) in the cell
DNA / genetic material
All new cells are derived from this
Other Cells
This organelle, only found in plant cells, is responsible for photosynthesis
Chloroplast(s)
Osmosis is a special type of diffusion involving these particles
Water
Growth, reproduction and this are the 3 main reasons why cells need to duplicate
Repair
These fibers are what helps pull chromosomes apart during cell division
Spindle fibers
The human body is composed of roughly how many cells?
Trillions and trillions!
It comes in both smooth and rough versions
Endoplasmic reticulum
Particles always move down the ______ due to diffusion
Concentration Gradient
Mitosis is one of this many phases of the Cell Cycle
3
This membrane breaks down during prophase as the chromosomes prepare to separate
Nuclear membrane
Plant an animal cells are both examples of this classification
Eukaryotes
This organelle is larger in plant cells, whereas animal cells have multiple smaller ones
Vacuole(s)
Cells placed in a hypertonic solution (e.g., salt water) where the solute concentration is greater outside will have this happen to them
Send out water / shrivel up
Cells spend the vast majority of their lives in this phase of the cell cycle
Interphase
After telophase, the chromosomes have arrived at opposite poles, and this final stage of the cell cycle can begin
Cytokinesis
Single-Celled organisms with no nucleus are classified as this group
Prokaryotes
The Golgi Apparatus carries out this function inside the cell
Receiving, packaging and sorting proteins
Particles that are too large to pass through the cell membrane on their own are able to move thanks to this
Facilitated diffusion / protein channels / active transport
Keeping this ratio within a certain limit is why cells need to reproduce instead of simply growing larger
Surface area : volume
Metaphase is the stage of mitosis where this happens
Chromosomes align in the middle
