The ancestors of plants that lived in water had plenty of water for the young. Angiosperms are a group of land plants that evolved a reproductive trait for living on land. This trait helps protect young plants by allowing them to grow only when water is present and the conditions for healthy development are right.

What trait most likely helped young angiosperms in this way?
A) cuticles
B) seeds
C) vascular tissues
D) photosynthesis

"Seeds" trait most likely helped young angiosperms in this way.

Option: B

Explanation:

Angiosperm, the largest and most abundant group within the Plantae Kingdom, one of about 300,000 species of flowering plants. Angiosperms compose about 80 per cent of all now existing known green plants. In an enclosed hollow ovary grows into a seed as angio are vascular seed plants where the ovule or egg is fertilized. Generally, the ovary itself is wrapped in a flower, that portion of the angiosperm plant which comprises the both male or female reproductive organs.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
