Is a root hair cell a prokaryotic cell
Root hair, or absorbent hairs, are outgrowths of epidermal cells, specialized cells at the tip of a plant root. They are lateral extensions of a single cell and are only rarely branched. They are found in the region of maturation, of the root.

WebTypically, the nucleus is the most prominent organelle in a cell. The nucleus (plural = nuclei) houses the cell’s DNA in the form of chromatin and directs the synthesis of ribosomes and proteins. Let us look at it in more detail ( Figure 3.11 ). Figure 3.11 The outermost boundary of the nucleus is the nuclear envelope.
Web23 mei 2024 · Root hair cells grow and reproduce more quickly than actual roots, which makes them great for biologists to study and learn about cell life. Their main (very important!) job is to absorb nearby water and nutrients. Sometimes, transferring a plant from one pot to another can cause the root hairs to fall from or get scraped from the plant. men\u0027s round gold sunglassesWeb2 From which cell organelle are nucleic acids absent?
