What are some characteristics of a seed plant? (There might be more than one answer)
- A.
Produce Seeds
- B.
Gametopytes don't live independently
- C.
Sperms need water to get to the eggs in order to fertilize them and make new plants
Correct Answer(s)
A. Produce Seeds
B. Gametopytes don't live independently
C. Sperms need water to get to the eggs in order to fertilize them and make new plantsExplanation
Seed plants, also known as spermatophytes, have several characteristics. Firstly, they produce seeds, which are reproductive structures containing an embryo and a food supply. This enables them to reproduce and spread their genetic material. Secondly, their gametophytes, which are the structures that produce gametes, do not live independently. Instead, they are contained within the sporophyte, which is the main body of the plant. Lastly, in seed plants, the sperm cells require water to reach the eggs and fertilize them, leading to the formation of new plants. This is in contrast to non-seed plants, where sperm cells rely on water for fertilization.Rate this question:

Correct Answer
Number of Cotyledons
Vein Types
Numbers of Flower Petals
Vascular Tissue PlacingExplanation
Monocots and dicots differ in several ways. One difference is the number of cotyledons, which are embryonic leaves found in the seed. Monocots have one cotyledon, while dicots have two. Another difference is in the vein types of their leaves. Monocots have parallel veins, while dicots have branching veins. Additionally, the number of flower petals can vary between monocots and dicots. Monocots often have flower parts in multiples of three, while dicots typically have flower parts in multiples of four or five. Lastly, the arrangement of vascular tissue also differs. In monocots, vascular tissue is scattered throughout the stem, while in dicots, it forms a ring.Rate this question:
