Chloroplasts and mitochondria are organelles found in plant cells. Chloroplasts contains the cholrophylls while the mitochondria is the powerhouse of the cell where energy is found. In this case, the two organelles not only have inner membranes but also their own DNA and ribosomes
<h2>Xylem;phloem and cork</h2>
Explanation:
Wood is mainly known as secondary xylem found in trees
- Xylem is basically the vascular tissue which is responsible for the conduction of water and nutrients from the roots to shoots and leaves
- Secondary xylem is formed from secondary growth and is associated with lateral growth and grows from the vascular cambium
- Its cell walls are thickened by deposition of lignin which provides mechanical support to plants and consists of tracheids and vessels that are shorter and wider
- In large woody plants secondary xylem get differentiated into heartwood and sapwood
Bark is essentially made of phloem and cork
- Bark sole purpose is to provide protection to trees
- The inner bark is produced by vascular cambium which consists of secondary phloem whose innermost layer transports food from the leaves to rest of the plant
- The outer bark is a dead tissue which is the product of cork cambium
Genetics combines Dna, technology, and agriculture
The correct answer is c. Postpartum psychosis is an extreme mental illness in which a new mother does not respond well emotionally to her new baby. This is not a voluntary disorder, which cancels out the first multiple choice option, and mothers who have diabetes actually seem to be protected from it, invalidating the second multiple choice option. The fourth multiple choice option seems to better describe postpartum depression, which is not the same as postpartum psychosis (the former is a depressive disorder, while the latter is a bipolar one).
