Gymnosperms are a more primitive, smaller category of plants that generate "bare seeds" (seeds that are not protected by a fruit). On Earth, there are still more than a thousand different types of gymnosperms.
What are the feature of gymnosperm?Several shrub species are also found, and these are often medium to large trees. Gymnosperms, which include some of the tallest tree species, including the sequoia.
The leaves, stem, and roots are the three distinct parts of the plant's body. Similar to conifers, the leaves have a thick cuticle, needle-like shape, and depressed stomata. This characteristic reduces water loss from transpiration.
The taproot system is the type of root system seen in gymnosperms. In some plants, these roots have a relationship with fungus and produce mycorrhiza, e.g. Pinus. While in certain other species, such as the Cycas plant, the roots take the shape of specialized roots known as coralloid roots and are linked to cyanobacteria that fix nitrogen.

Why element of the xylem in vascular bundle is less than the phloem?
Answer:
The element of the xylem in vascular bundle is less than the phloem because the Xylem carries water which is a raw material to manufacture the food.
Explanation:
A pair of xylem and phloem is termed to be a 'vascular bundle'.
The purpose of the Xylem tissue is to transport the water from the roots to the stems and leaves. Other compounds are also transported which are dissolved in the water. Phloem, on the other hand, helps in transporting food from leaves to other parts of the plant.

Drag each label to the correct location on the map.
Identify the types of precipitation on the map. The color scale gives the rainfall amounts in inches.
The given question is incomplete as it lacks the map which is important, however the correct answer is attached:
Answer:
The correct answer is -
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.
Explanation:
As per the map and the scale presented on the map that indicates the rainfall in inches. The green area indicates that the rain fall in this area is one inch which is moderate as the the sky blue rainfall measurement is .5 inches which is half. However, the red area is the highest rainfall area in comparison to both of these which is about four inches.
On the basis of these it we can label all three boxes as per their rainfall amount that is,
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.

Which of the following statements concerning metagenomic sequencing is incorrect
Answer:
The correct answer is "proteins are extracted from an environment, fragmented, and adaptors are added".
Explanation:
The missing options of this question are:
A) Software aligns sequences and assemble large portions of genome.
B) The samples are subject to polymerase chain reaction for amplification.
C) The sequences of the amplified fragments are determined by next-generation methods.
D) Proteins are extracted from an environment, fragmented, and adaptors are added
The correct answer is option D) Proteins are extracted from an environment, fragmented, and adaptors are added.
Metagenomic sequencing refers to the amplification and determination of all nucleotide sequences in a sample, which might contain multiple microorganisms and viruses in order to understand the presence and proportions of microbiota. Metagenomic sequencing involves the use of next-generation methods, to amplify and characterize all the nucleotides sequences. It is false to affirm that the proteins are extracted directly from the environment in this technique, since metagenomic sequencing is focused on the nucleotide sequences.

Describe the trends that you see in the evolution of land plants in terms of: gametophyte or sporophyte dominance size and independence (whether or not it can live on its own) of the gametophyte or sporophyte Make sure that you identify those two traits for each of the major land plant groups : 1) "Bryophytes" 2) Ferns and Lycophytes 3) Seed Plants (Gymnosperms and Angiosperms) New piece of information: diploid organisms have higher survival under high ultraviolet radiation environments (i.e. on LAND!) than haploid organisms. Using the trends you observed and the new information above, make an inference: WHY do we observe these trends in the land plants? (In other words, how might higher survival of diploid organisms under high UV conditions explain the trend you observe.)
Answer:
Explanation below.
Explanation:
Gametophytes are plants that reproduce not by spores but by gametes, that is male and female gametes.
Sporophytes are the plants that make use of spores as the means of reproduction. This means that they produce spores.
1. Bryophytes are sporophytes
2. Fern or lycophytes are sporophytes
3. Seed plants are gametophytes. And that is why they possess both male and female gametes.
