I took this picture of this plant using my phone. The thin brown stalks that you see are.
approximately 2 centimeters tall (a little less than 1 inch).
The flat green leaves of this plant represent:
The sporophyte generation
The gametophyte generation
READ THE FOLLOWING INSTRUCTIONS:
Bryophytes in which the gametophytes are "leafy" in appearance and the sporophytes grow conspicuously from the tips of the gametophyte plants.
STEP 1: Examine the mass of moss plants and then select one or two individual gametophyte plants and note the leaf-like (not true leaves because they lack conducting tissue) structures which are arranged around a central, vertical "stem-like" stalk and root-like rhizoids which anchor the plant and absorb water and nutrients.
STEP: The sex organs are in the tips of the plants and must be seen with the microscope. Study a slide of a vertical section through head of a mate plant and note the many antheridia.
STEP 3: Examine a slide through a vertical section of a female plant. Note the many upright archegonia each on a tall stalk and each with a swollen base or venter containing an egg and an elongate neck. Note the filamentous paraphyses between the archegonia.
STEP 4: Examine a living or preserved…
Plants Are Adapted to Life on Land
Plants developed from a group of green algae (members of Kingdom Protista) called the charophytes. Like these green algae, plants have a life cycle called the alternation of generations. Draw a diagram of the basic life cycle of a plant, showing the alternation of the sporophyte and gametophyte generations.
Unlike green algae that live in water, plants live on land. Being surrounded by air means that they risk losing too much water through evaporation and dying from dehydration. Name 3 characteristics of plants that help them conserve water and protect them from drying.

The researchers did an experiment where they added a hormone that reduces the production of alkaloids. In graph (a), the data show that the hormone reduced the proportion of alkaloids as a function of leaf mass relative to controls- so the hormone worked. They also measured the lifetime seed production of the plants in both treatments without any herbivores present (b). They had the following results.

This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forward
