Are membrane-bound sacs filled with digestive enzymes?
lysosome are membrane bounded sac filled with hydrolytic enzymes. they are also called sucide bag of cell.
Which organelle contains digestive enzymes that break down substances?
What part of the cell contains enzymes that break down materials?
Which cell part contains enzymes to digest foreign materials?
Which two organelles are sacs of enzymes?
10)Which two organelles are sacs of enzymes, and what is the function of each of these organelles? Lysosomes break down ingested bacteria, worn-out organelles, and dead cells. Peroxisomes detoxify a number of harmful toxic substances and disarm free radicals.
What are the two main stages of cell division in eukaryotic cells?
In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.
Why do normal cells grown in a petri dish tend to stop growing?
The normal cells when grown in a nutrient medium starts growing in into the petri dish. The cells keep on growing and when the bottom layer of the plate is filled with the cells then the cells in the petri dish stops growing. This is because the cells observes the contact of one cell with another.
What determines how much waste is produced in a cell?
The rate at which nutrients are used up and wastes are produced depends on the cell’s volume. Does the volume of a cell increase faster than its surface area? Yes, As the length of a cell increases its volume increases faster than the surface area.
What are problems that growth causes for cells?
What problems does growth cause for cells? The larger a cell becomes, the more demands the cell places on its DNA. In addition, the cell has more trouble moving enough nutrients and wastes across the cell membrane.
