<u>Gymnosperms and Angiosperms-</u>

Gymnosperms and angiosperms evolved seeds and pollen grains allowing them to live and reproduce in drier habitats than bryophytes and seedless vascular plants.

<u>Properties of gymnosperms and angiosperms-</u>

Gymnosperms are plants which bear seeds without fruits or without any outer coverings. These plants also do not produce flowers. Most plants under this group have needle-shaped leaves. This is an adaptation as these plants grow in colder conditions. Gymnosperms. These plants produce pollen without bearing flowers. Angiosperms are found in almost all climatic conditions. These plants bear flowers and produce seeds that are enclosed inside a fruit or inside an ovary. The seeds of angiosperms have a single cotyledon.

Explanation:

A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>

I annexed an image of the DNA structure.

Anit [1.1K]

In the spermatheca, females of many insect species, including honeybee queens, can store gametes secreted by their sex partners.

<h3>What is Spermatheca ?</h3>

The female insect's spermatheca is an ectodermal structure that receives, stores, and releases sperm for egg fertilization. According to the species, spermathecae differ in size and shape.

  • They often come from the median oviduct, which is located close or on the genital chamber. A secretory duct called the ductus seminalis connects the spermathecal sac, also known as the receptaculum seminis, to the genital chamber, where the sperm are released.
  • The number of spermathecas varies among taxa, however the majority of insects only have one. Depending on the species of insect, the spermatheca has different morphologies. The spermatheca is composed of the spermathecal gland, duct, and reservoir. Both of these fluids feed the sperm. Both the spermathecal glands and the male accessory glands secrete substances that feed the sperm.

So lastly we can say that, t females of many insect species, including honeybee queens, can store gametes shed by their mating partners in - the spermatheca.
