<h2>Permanent tissues in Plant</h2>
Explanation:
A) The cell walls of parenchyma cells are thinner than those of sclerenchyma cells
Plants posses basically two kinds of tissue- meristematic tissue and permanent tissue.
Meristematic tissue is made up of cells which are capable of active division and give rise to other tissues,.
Permanent tissue are already differentiated and usually do not divide.
Permanent tissues are -collenchyma, sclerenchyma and parenchyma.
Parenchyma and collenchyma are living whereas sclerenchyma is non-living.
1. The virus attaches itself to a host cell
2. The virus inserts its nucleic acid into the host cell
3. The virus nucleic takes over the host cell and makes virus parts
4. The cell creates more viruses
5. The cell bursts, releasing the new viruses
D) Contour plowing is used to reduce erosion and sediment pollution.
Explanation:
Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.
Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.
- The rate at which rain water and precipitation moves along slope terrain is very fast.
- This causes the washing off of the the topsoil on hills to eroded very fast.
- Contour plowing breaks the slope and farming is done along movement on the contour.
- This prevents topsoil erosion.
- It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.
