Answer:
A pollen tube grows from the pollen grain into the ovary
Explanation:
Water is needed for fertilization in several plant groups because the sperm needs to swim to meet the non-motile eggs of the female organs.
<em>However in angiosperms, the pollen germinates and a structure known as pollen tube which contains the male gametophyte (sperm) grows into the ovary where the ovule is located and the male gametophyte is deposited in the ovule to initiate the fertilization process.</em>
<em>Hence, water is really not necessary for fertilization in the angiosperms.</em>

Explanation: protists are mainly
Unicellular organism( i.e they are single cell organism) and are eukaryote( they have a nucleus) but some protist exist as multicellular example is some Algea, kelp. They can be find in moist environment.
Protist can be grouped into the
1. Animal protist are heterotrophs and they depend on autotrophs or producers for their food or other organism and are mobile( they move)
2. Plant protist are mainly autotrophs they have ability to synthesis there food through photisynthesis.
3.Fungi protist reproduce using spores. They are heterotrophs.
Some protist move by pseudopodia while some uses flagella.
Hence protein are not mainly multicellular eukaryotes but both unicellular and multicellular eukaryotes.
