Heterospory, highly reduced gametophytes, ovules, pollen, seeds are the five adaptations common to all seed plants that ensure their success in the adaptation to land. Three things: The gametophytes of seed plants are reduced and dependent upon the parent sporophyte which protects them (particularly in the case of the female gametophyte). Pollen is covered with sporopollenin which is resistant to physical factors in the environment. The structure of the seed protects the next generation sporophyte and allows it to remain dormant until conditions are right for germination, development and growth.
The human body is organized at different levels, starting with the cell. Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems.
Answer:
The relative frequency of an allele is all the genes that are present in a the gene pool of a population
Explanation:
Answer: The tissue structure of the liverworts restricts them to a type of environment that affects their size.
Explanation:
Nonvascular plants, also called the Bryophytes in Kingdom Plantae, are simple plants that grow in damp places on land and as the name implies, are non vascular plants( that is, they lack vascular tissues). There are three types of nonvascular plants which includes:
--> Mosses
--> liverworts and
--> hornworts.
Liverworts are restricted to a particular size through the type of tissue they have ( non vascular) because it predisposes them to lack conducting vessels like the phloem and xylem found in vascular plants which aids in conducting water and food to various parts of the plants. Also they do not grow tall like the vascular plants because they lack the qualities that will enable them do so, such as roots, stems and leaves.
Nonvascular plants are low-growing, reproduce with spores, and need a moist or damp environment.
