The main role of chloroplasts<span> is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water</span>
Answer:
The missing step is oxygen is removed from the water after step 3.
Explanation:
The steps listed by Xavier are:
- <em>Water is drawn in trough pores and enters the central cavity.
</em>
- <em>Food is filtered and digested.
</em>
- <em>Water leaves trough an opening at the top of the body.</em>
Porifera or sponges are aquatic, immobile invertebrates whose structure is saccular with an upper opening, the osculus.
Sponges absorb water through their pores, where the porocytes are found, and through flagellated cells -the coanocytes- the movement that allows the entrance of water to the spongocele or atrium is produced, in addition to the phagocytosis of organic elements.
Once the water is in the interior chamber of the sponges, the organic particles are phagocyted to be digested, and the oxygen is removed from the water, and passes through diffusion into the cell. The waste products, as well as carbon dioxide, are released into the water that will be expelled through the osculus.
<u><em>In Xavier's list, the missing step is the removal of oxygen from the water, before it is expelled from the body of the sponge</em></u><em>.</em>

A single cell RNA seq analysis identifies 25 population of epidermal cells .
<h3>What is single cell transcriptomics used for?</h3>
Single cell transcriptomics are being used to create reference maps of healthy human tissues, organs and systems at single cell resolution.
An essential model system for studying stem cells and tissue regeneration is the mouse epidermis with its hair follicles. To demonstrate how the cellular heterogeneity of the murine telogen epidermis is controlled at the transcriptional level, we used single-cell RNA-sequencing in this study. 25 different populations of interfollicular and follicular epidermal cells were identified by impartial clustering of 1,422 single-cell transcriptomes. With previously unheard-of resolution, our data allowed for the reconstruction of gene expression patterns during epidermal development and along the proximal-distal axis of the hair follicle.
