Lettuce and spinach has a semi permeable membrane
since it's put into water, which water has a higher water potential than the leaf cells, water molecules will pass from the water to the cells through the membrane by osmosis . this leads the cells to be turgid and therefore the lettuce and spinach becomes firm

In flowering plants what structure containing DNA is transported from one plant to another
azamat

Answer:

Pollen

Explanation:

Flowering plants are plants classified as Angiosperms. They are the most diverse group of plants in the Kingdom Plantae. Angiosperms or flowering plants as their name implies are characterized by the possession of reproductive structures called FLOWER. The male reproductive flower called STAMEN produces their gamete in a structure called POLLEN while the female reproductive flower called PISTIL contains an ovary that produces egg cells called OVULES.

In flowering plants, the pollen of a male flower is transported to the receptive part of the female flower called STIGMA in a process called POLLINATION. The pollen contains the gamete (sperm cell) that conveys the genetic material (DNA) of the male plant. A fertilized ovule develops into a seed, hence, the reason flowering plants are called SEED-BEARING.

Therefore, pollen is the structure containing the genetic material (DNA) that is transported from one plant to another (same species) in flowering plants.

Climate characterized by mild temperatures is ______. Question 4 options: tropical humid dense temperate
Pachacha [2.7K]

The correct answer is - temperate.

The temperate climates can simply be described as climates with milder temperatures. These climates have changes of seasons, four of them, spring, summer, autumn, and winter. The springs and autumns tend to have mild temperatures, the summers are warm, and the winters are cold, but the highest and lowest temperatures do not come close to the extremely high temperatures in the tropical zone, or extremely low temperatures in the high latitude zones. So these climates have temperatures that are in between the extremes of the low and high altitudes, thus they are milder climates.

BlackZzzverrR [31]

Answer:

Evaporation – Evaporation happens when heat from the Sun turns liquid water into water vapor (gas). About 90% of the water in the atmosphere comes from evaporation. Most evaporation occurs in the oceans, because they cover so much of Earth's surface. The sweat evaporates into the air.
