13) Please just give me the answer, ( ignore my selection), Please just say the answer.
The kingdom Plantae is also known by the name of the kingdom Metaphyta. This kingdom includes all types of multicellular and photosynthetic plants that are found in the biosphere. The plants are autotrophs in nature, meaning that they synthesize their own food with the help of solar energy.

- The Riccia is a bryophyte because: It has multicellular sex organs with a sterile jacket and lacks vascular tissues Its sporophyte lacks differentiation and has a single- layered jacket It occurs mostly on land and has more motile sperm It has a heteromorphic alternation of generation and lacks leaves NextOne of the genera of Lycophytes are the Selaginellaceae. Like other Lycophytes, Selaginellids bear their spores in a strobilus but they have an unusual strobilus. Which answer below best describes this difference?

Lack roots, stems and leaves Include mosses, hornworts and liverworts only Sporophyte is the dominant generation Possess a waxy cuticle to prevent water lossAfter following the life cycle of an unknown plant species, you determine it's life cycle in the following order: sporophyte -> meiosis -> gametophyte -> gametes -> double fertilization -> diploid zygote.

They generally have only tracheids for water conduction and lack vessel elements, which are characteristic of angiosperms. Tyino I. Division: Cycadophyta Although there is only about 100 extant species of cycads, this phylum was significant during the Triassic period (248 million years ago). They are tropical and subtropical plants with trunk-like stems and compound leaves and are popular as ornamentals. These plants are dioecious in that seed cones and pollen cones are on two separate plants. Because of their palm-like structure, they are sometimes incorrectly described as palm trees. However, like other gymnosperms they produce cones and lack flowers. Examples of cycads include False king sago and Florida coontie (Zamia pumila). Zamia pumila is the only cycad native to the United States. ACTIVITY 1: Examine the live plant and/or cones if available. (Use the atlas if necessary.) olsmot…
