Vegetative reproduction is a mode of asexual reproduction naturally occurring in plants. In this process. only one of the parent is involved and the offspring is genetically identical to the parent and no sharing of DNA takes place.
Examples are: Onion, rhizome (ginger) and daffodil
Explanation:
There are meristem tissues found in the stem, root and leaves. These are undifferentiated cells and have tendency of dividing. This tissue gives rise to organs of the plant and responsible for its growth.
Natural vegetative propagation happens when an axillary bud grows into a lateral shoot and develops adventitious roots consequently forming a new plant.
Vegetative propagation can be done artificially also.
Answer:
Ectotherms warm their bodies by absorbing heat from the surrounding environment, whereas Endotherms produce heat by their metabolic activities. • Ectotherms have large variations in normal body temperatures while endotherms maintain their body temperature in a fairly constant value
Explanation:
Answer:
c. Proteins and lipids are made on the ER membrane and put in vesicles.
a. Vesicles containing proteins and lipids fuse with the Golgi bodies.
d. The Golgi bodies tag the molecules to signal their ultimate delivery.
b. Vesicles pinched off from the cristernae carry the molecule to its location.
Explanation:
Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
