Biology

Tree rings are annual growth rings and their thickness indicates how growing conditions were for that year. Index fossils in their type and frequency are indicative of the environment that those organisms grew in and how prolific life was then in that environment. Ice cores drilled through glaciers and ice sheets like in Antarctica tell us about such things as the concentration of greenhouse gases like carbon dioxide (as bubbles in the ice layers) and also about climatic  conditions in glacial and interglacial periods.

Fed [463]

Answer:

a. a female reproductive structure

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.

Division Antophyta are classified into two (2) main categories and these includes;

I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.

II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.

Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.
