What early concept of cells was eventually disproved as a result of the research that led to the development of cell theory?
The idea was they believed that protoplasm was the same in all cells.
When was the cell wall born?
At the same time the cell was created. Cells reproduce by diving themselves in half, so a single cell with a cell wall to hold in its protoplasm simply pinches together in the middle until it become two separate cells with cell walls.
What are the main parts of the cell?
If it is an animal cell, then it's 9 parts are the vacuoles, the Golgi body, the cytoplasm, the mitochondria, the cell membrane, the lysosomes, the nucleus, the endoplasmic reticulum, and the ribosomes. If it is a plant cell, it has a lot of the the same parts, but some different ones. There are 10 parts in a plant cell. The endoplasmic reticulum, the Golgi body, the vacuoles, the cell wall, the cytoplasm, the cell membrane, the chloroplast, the mitochondria, the ribosomes, and the nucleus. I got this from a science book.
What does protozoa look like?
Protoplasm is the living content of a cell that is surrounded by a plasma membrane. This term is not commonly used in modern cell biology. Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules such as nucleic acids, Proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell's center is known as the cytoplasm and that inside the center as the nucleoplasm. In prokaryotes the material inside the plasma membrane is the bacterial cytoplasm, while in gram-negative bacteria the region outside the plasma membrane but inside the outer membrane is the periplasm.Protoplasm is distinct from non-living cell components lumped under "ergastic substances" or inclusion bodies, although ergastic substances can occur in the protoplasm. In many plant cells most of the volume of the cell is not occupied by protoplasm, but by "tonoplast", a large water filled vacuole enclosed by a membrane. A protoplast is a plant or fungal cell that has had its cell wall removed.My source is linked below.
Is the gamete cell formed in fertilization the same or different than the parent cell?
Same
It is said that protoplasm cannot be analysed chemically.why?
The chemical composition of protoplasm is very complex.It varies a little from one cell to another, although the common elements included in the composition of the protoplasm are the same in all cells.However it is impossible to make an accurate chemical analysis of protoplasm as it ceases to be protoplasm only as soon as it is removed from the organism.Not accurateIt can be analyzed chemically. With todays methods, pretty much anything that is stable and doesn't decompose can be analyzed chemically. Protoplasm is no different.

Protoplasm found outside the nucleus?
The protoplasm found outside of the nucleus is called cryptoplasma. The cryptoplasma's function is the same as the protoplasmas, which is to protect the nucleus.

Same
Is it true that Protoplasm constantly changes shape?
no they are all ways the same shape
Is the nucleus of a plant cell different than animal cell?
No I think they are both the same as they do the same things in each cell
Is a cells live the same for every cell?
no. every cell is different
2 numbers thaty have the same absolute value but diffeent signs?
1 and -1 They are both 1 number away from 0
What causes the differences between two human cell types?
contain same genes, but uses different combinations of them.
