23. Which cell organelle is responsible for the release of energy as ATP?
25. What are the basic functions of cell.​

Answer 1

1. Nucleus
2. Chromosome in Nucleus
3. Gene are the heredity material passed to next generation.
4. Through pseudopodia or false feet
5. Ribosomes
6. Chloroplast which is a plastid
7. Lysosomes
8. Mitochondria
9. Endoplasmic reticulum makes phospholipids which is used to make the plasma membrane. This process is known as membrane biogenesis.
10. Leucoplast is colourless while chromoplasts are colourful. Leucoplast store starch, oil and lipids whereas chromoplast give colour to fruits and flowers.
11. Golgi Apparatus helps in packing and dispatching the material made by the Endoplasmic Reticulum.
12. The two types of cell division are Mitosis and Meiosis.
13. Osmosis need membrane but diffusion don't need membrane.
14. Schwann
15. cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
16. Robert Hooke
17. Chloroplast
18. The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall
19. Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.
20. However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs. For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not.
21. in image above...
22. It is suicidal bags of the cell.
23. All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
24. Mitochondria
25. the seven life processes are the seven things that a cell must do to be able to be considered a living cell. The seven processes are movement, reproduction, response to external stimuli, nutrition, excretion, respiration and growth.
