Answer:
The stigma becomes moist and sticky at maturation allowing for the pollen to be captured. The top of the pistil being enlarged offers a greater surface area for pollen to land on as well.
Explanation:
When you cross two heterozygotes with the genotype Aa, the offspring will be: <span>Parents: Aa x Aa</span>
<span>F1 generation: AA Aa Aa aa</span>
<span>This means that ½ of the offspring will be heterozygous, ¼ will be homozygous (dominant) and ¼ will be homozygous (recessive).</span>
Answer:
1. Apoplastic
2. Symplastic
3. Symplastic
4. Apoplastic
Explanation:
The interconnected porous cell walls of plant cells make apoplast along which water is allowed to move freely. Symplast refers to the path made up of interconnected cytoplasm of many plant cells connected by plasmodesmata. Therefore, water and dissolved minerals enter the root cortex from the epidermis in the solution can move through symplast and apoplast till endodermis.
Water and dissolved minerals present in the cytoplasm of cortical cells move from one cell to next via plasmodesmata (the symplast) while the ones present in their cell walls and intercellular space move through apoplast. The presence of casparian strips in the endodermal cell wall does not allow the movement of water and minerals through the apoplast.
