Angiosperms and life on land Many aspects of the angiosperm life cycle make flowering plants particularly well-suited to life on
vova2212 [387]
<h2>Angiosperms </h2>

Explanation:

Angiosperms are the most diverse group of plants, some statements which reflect angiosperm adaptations to life on land:

  • Flowers attract animal pollinators carrying pollen from other plants of the same species
  • Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits
  • In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators
  • Floral parts of the sporophyte protect the reduced female gametophyte from drying out and from UV radiation
  • Seeds protect and nourish plant embryos, and fruits protect the seeds
  • Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals

Describe the similarities and differences in the way humans and insects obtain oxygen.
Molodets [167]

Answer:

There are many ways.

Explanation:

Humans have a combined respiratory and circulatory system, whereas insects do not. In humans, the air is brought in through the mouth/nose, through the windpipe, and into the lungs, the oxygen is absorbed into the bloodstream where it can be transported to muscles and organs. However, insects take in air through tiny holes in their thorax and abdomen. These are called spiracles. The oxygen is stored in many dorsal air sacs to be used. Then carbon dioxide is expelled through the spiracles.
