1) Robert Hooke was the first person to describe cells.
2) Anton van Leeuwenhoek
3) Matthias Schleiden was one and he concluded that all plant cells were made of cells. Another scientist was Theodor Schwann and he concluded that all organisms are made up of one or more cells and the cell is the basic unit of all living things. The last scientist was Rudolf Virchow and he concluded that all cells come from exsisting cells.
4) The three parts of the cell theory are that all organisms are made up of one or more cells, the cell is the basic unit of life, and all cells come from existing cells.
5) Prokaryotes and eukaryotes are alike because they are both common cells but differ because eukaryotes have a true nucleus and prokaryotes don’t and also prokaryotes are bacteria cells and eukaryotes aren’t.
6) Extremiphiles are heat-loving, salt-loving, and methane making and they live in extreme condition places. They are located hot water, such as hot springs, and they can also live in extremely salty water.
7) The most common type of bacteria is eubacteria and eubacteria is found almost everywhere.
The function of the nucleus is to provide structural support for cells, send messages to make protein, control the cell, and make DNA. The material in the nucleus is DNA.
9) Did you mean where is the nucleoulus found because i dont get what “why the nucleoulus is found” but if you meant where is it found then its found in the nucleus and it makes ribosomes.
10) The function of the smooth ER is to make lipids and break down toxic materials that could damage the cell. The rough ER’s function is to deliever protein through the cell.
11) Mitochondria is important because is the main power source of the cell and contains mitochondrians which make sugar into energy.
12) The golgi bodie’s purpose is to package and distribute proteins. The golgi bodie makes vesicles.
13) Lysosomes.
14) Vesicles are small sacs that surround materials to be moved into or out of a cell. Plant cell vesicles are different than animal cell vesicles because they have vacuoles and animal cells have lysosomes.
15) The function of the ribosomes are to make protein and you can find them floating freely in the cytoplasm or attached to membranes or the cytoskeleton.
16) The cytoplasm is the floating liquid in the cell and it relates to the Jell-O lab because the Jell-O freely floats in the cup just like how the cytoplasm freely floats in the cell.
17) The purpose of the cell membrane is to protect the cell and keep bad stuff out of the cell.
18) The difference between animal and plant cells is that plant cells have a cell wall, have chloroplasts, go through photosynthesis, have a large vacuole in the center, and are rectangular. Animal cells don’t have a chloroplast, don’t go through photosynthesis, do not have a cell wall, has one small vacuole, and has either a circular or irregular shape.
19) Cell types that have cell walls: Plants, bacteria, and certain types of fungi.
20) You will find the chloroplast in plant cells and its function is to make food for plants.
21) The produce department has a sprinkler system so it can keep the fruits and veggies fresh and clean.
22) Positive aspects of bacteria: Bacteria can convert the sugar from yogurt and milk into lactic acid which will cause milk to thicken and also bacterica helps food digest. Some bad things about bacteria, however; is it can cause diseases in humans, plants, and animals which could kill them.
23) Cells make tissues, tissues make organs, organs make organ systems, organ systems make organsims.
