What function of cuticle on the upper surface of the fern leaves?
reproduction
Is megaspore involved in the reproduction of Botrychium virginianum?
Yes, megaspores are involved in the reproduction of Botrychium virginianum, commonly known as the Virginia grape fern. This plant reproduces via spores, with megaspores developing into female gametophytes. The megaspores are produced in specialized structures called sporangia and play a crucial role in the fern's life cycle, facilitating sexual reproduction.
What type of taxis is a bacterial cell exhibiting when it moves toward glucose in the environment?
Chemotaxis - this is the general term for bacterial motility when sensing a compound in the environment. If moving toward it is called positive chemotaxis, if away from it is negative chemotaxis.
What are the brown spots on the back of java fern leaves?
The brown spots on the back of Java fern leaves are likely sporangia, which are structures that produce and release spores for reproduction. They are a natural part of the plant's life cycle and do not necessarily indicate a problem with the plant's health.
What are the shoots coming out of a fern they look like string?
The shoots coming out of a fern that resemble strings are called "fronds." These are the leaf structures of the fern and typically unfurl from tightly coiled bundles known as "fiddleheads." As they mature, fronds develop into the characteristic leafy structures of the fern, playing a crucial role in photosynthesis and reproduction.

What is the curled up frond a fern called?
The uncurled leaves of a fern are called fronds. A fern is a autotroph. Ferns need to release their spores into moist environments in order for reproduction to occur.

What is shape of prothallus of fern?
flat.heart-shaped membranous structure with numerous rhizoids on its central lower surfaces.
