Answer:
Male cones produce microspores.
Pollen grain contains cells that develop into sperm.
Explanation:
Gymnosperms are seed-bearing vascular plants. They produce cones and seeds to carry their reproductive structure. They produce both types of cones (male and female) for fertilization by making gametes. Male cones produce microspores to make pollen grains. Female cones give rise megaspores which produce ovules. Pollen grains spilt up to make sperm. One of these sperms fuse with egg cells for the fertilization.
The eye spot and the chloroplasts work together to help the euglena survive because the eye spot senses the light and the dark. Since euglena need to do photosynthesis in which uses light energy to make usable energy, to get food, the eye spot will tell the euglena where to move in order for it to be able to do photosynthesis.
Answer:
ubiquitin targets CDKs
Explanation:
Cyclins are named such because they undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex. This complex then acts as a signal to the cell to pass to the next cell cycle phase.
Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.
